They are working in a new installer, it will be ready soon, but dont know when. The 1st step to see if the installer is corrupted is to check if the file you downloaded have the same size that the download site said. You also can check for alternative download places in my signature, press where it said "show": but all of them are 1 year old, you will need to update a little, maybe you can download the manual patches or use the unoficial patchers (for all that also check my signature).

I originally downloaded it from the website after i finished registering.
Then after i would play for a bit then log off then when i would i want to play again it would not let me.
I looked through a few old topics on here and i will be attempting to use the idea of allowing it through the norton firewall.
After i download it from meaupload because the website would not allow me to download it >.>

When reinstall, try to delete the remaining files in the requiem folder, and reset the pc before install again. You can search for more guides in my signature (press the "show" button). If you could play at least for some time, then the client probably is fine, the problem probably is with something in your windows blocking the game from start.

So what do you do after you find out you do or don't have a corrupt file?

Which was your exact problem? Which windows, firewall and antivirus do you have? From where you downloaded the game and which version of the game you have? (to know which version you have, go to the Requiem folder and open the version.dat file with notepad, then post the text inside in this thread).
